Sony has released the second generation of its ePaper watch. The price has gone up - the FES Watch U now starts at JPY 46,000 ($420/) and goes up to JPY 60,000 ($545/) for the premium model (the original was JPY 30,000). Like before, this watch is exclusive to Japan.

The FES is less about being a smartwatch and more about personalized design. You see, the screen and the wrist band are a single ePaper display. This means you get to customize the look of the band and some really cool-looking designs are possible.

The watch itself comes has an IP67-grade body (43mm case diameter, 12mm thick) and weighs 75g. Its batter should last 2 weeks. The Premium Black model features a Sapphire glass and Ion plating, the regular Silver and White models use Mineral glass.

Just some of the many possible designs you can use with the FES U

You can hook it up to an Android or iOS device over Bluetooth 4.0 to control the design of the watch with the dedicated app. You can download ready-made designs (free and paid) and make your own with the camera. By the looks of it, notifications are not supported.
